Appendix A: Supplementary figures

In Figs. A.1 and A.2, we show results at a radius of 10 AU from the same models described in Figs. 12 and 14.

In Figs. A.3 to A.6 we show the fractional abundances

as a function of radius, R, and height scaled by the radius, Z/R, for those species not discussed in detail in the text. These include important oxygen- (e.g., O2, CO, and CO2), carbon- (e.g., CnHm) and nitrogen-bearing species (e.g., N2 and NH3).

Fractional abundance with respect to gas number density of N (top row), N2 (middle row), and HCN (bottom row) as a function of Z/R at R = 10 AU for each disk model. The black dashed lines, purple solid lines, and green solid lines represent results from the fiducial model (including N2 shielding and X-rays), the model with N2 switched off, and the model with X-rays switched off, respectively.

Fractional abundance with respect to gas number density of N2 (top row), NH3 (middle row), and HCN (bottom row) as a function of Z/R at R = 10 AU for each disk model. The black dashed lines, orange lines, cyan lines, green lines, and gold lines represent results from the fiducial model and a model in which (i) all species are initially atomic; (ii) all nitrogen is in N2 gas; (iii) all nitrogen is in N2 ice, and (iv) all nitrogen is in NH3 ice, respectively.

Fractional abundance relative to total gas number density of oxygen-bearing species for the M dwarf disk (left-hand column), T Tauri disk (middle column), and Herbig Ae disk (right-hand column). The dotted and dot-dashed lines indicate the dust column density (integrated from the surface downwards) at which τ 1 at 3 μm and 14 μm, respectively.

Fractional abundance relative to total gas number density of carbon-bearing species for the M dwarf disk (left-hand column), T Tauri disk (middle column), and Herbig Ae disk (right-hand column). The dotted and dot-dashed lines indicate the dust column density (integrated from the surface downwards) at which τ 1 at 3 μm and 14 μm, respectively.
